修复 WxCpApprovalWorkflowDemo.java 的 Java 8 兼容性和编译错误

[Copilot]

PR #3687 引入的演示代码使用了 Java 10+ 的 var 关键字，且调用了不存在的方法导致编译失败。

修复内容

Java 8 兼容性

• 添加 import me.chanjar.weixin.cp.bean.oa.WxCpOaApprovalTemplateResult
• var templateResult → WxCpOaApprovalTemplateResult templateResult

方法调用修正

• detail.getSpStatus().getCode() → detail.getSpStatus() (枚举类型无 getCode)
• detail.getApplyer() → detail.getApplier()
• detail.getSpRecord() → detail.getSpRecords() (数组字段)
• record.getSpStatus() → record.getStatus()
• approvalInfo.getCount() → approvalInfo.getSpNoList().size()

// Before
var templateResult = wxCpService.getOaService().getTemplateDetail(templateId);
System.out.println("审批状态: " + detail.getSpStatus().getCode());

// After
WxCpOaApprovalTemplateResult templateResult = wxCpService.getOaService().getTemplateDetail(templateId);
System.out.println("审批状态: " + detail.getSpStatus());

Original prompt

Issue

The test/demo class weixin-java-cp/src/test/java/me/chanjar/weixin/cp/demo/WxCpApprovalWorkflowDemo.java currently uses Java local variable type inference (var) in templateManagement(), which causes compilation failures in projects/builds using Java 8. The demo file is also missing an explicit import for WxCpOaApprovalTemplateResult.

Goal

Create a small change to make the demo Java 8 compatible by replacing the use of 'var' with an explicit type and adding the required import. Keep all other code unchanged.

Files to change

1. weixin-java-cp/src/test/java/me/chanjar/weixin/cp/demo/WxCpApprovalWorkflowDemo.java

Change details

• Add import: me.chanjar.weixin.cp.bean.oa.WxCpOaApprovalTemplateResult
• In templateManagement(), replace:
  var templateResult = wxCpService.getOaService().getTemplateDetail(templateId);
  with:
  WxCpOaApprovalTemplateResult templateResult = wxCpService.getOaService().getTemplateDetail(templateId);

Provide the updated file contents (full file) below. This is a minimal, non-behavioral change intended only to fix compilation on Java8.
